What is crawl ratio on a Jeep?
A crawl ratio is simply the ratio of torque at the wheels to torque at your engine’s flywheel. It represents how many times your engine torque is multiplied before it gets to the place where the actual propulsion occurs.
What gear ratio does a Jeep Liberty have?
Stock Gear Ratio Table
| 2.4L (2002–2004) | 3.7L (2005–2006) | |
|---|---|---|
| Automatic | 4.10 | 3.73 |
| Manual | 4.10 | 3.55 |
What is 4×4 crawl ratio?
Crawl ratio is a term used in the automotive world to describe the highest gear ratio that a vehicle is capable of. However, for a given engine speed and a gear ratio, the output force on the road wheels decreases as the tire size increases. A lower force in turn decreases the acceleration of rotating wheels.
Are 3.73 gears good for off-road?
Larger tires can provide clearance and traction, but they will also give your 4WD sluggish acceleration. For example, if you have 3.73 rear axle ratio and 33” tires, you’re going to have very poor acceleration. To correct it, you could swap out to a lower 4.27 rear axle gear and get more torque and faster acceleration.
What gear ratio is best for off roading?
Not all gear ratios are available so you have the choice between 4.88 and 5.13, 4.88 being the closest. Choose a little bit lower gear ratios if you do a lot of off-road driving and a little bit higher if you do more long distance highway trips.
What are 4 56 gears good?
4.56 gears are better for acceleration owing to their increase of rear-wheel torque. Note that as the ratio number goes up, the trucks relative speed goes down, since the engine can only turn so fast.
What gear ratio do I need for 35 inch tires?
Gear Ratio And Tire Size Calculator
| 3.31 | 5.71 | |
|---|---|---|
| 34″ | 2126 | 3668 |
| 35″ | 2065 | 3563 |
| 36″ | 2008 | 3464 |
| 37″ | 1954 | 3370 |
What gear ratio is best for 31 inch tires?
The 4.10 gears are in general good with 31″ tires. The 3.0 engine is not great on torque so it would probably benefit with lower gears.
What gear ratio should I run with 37 inch tires?
Upgrading to 37-inch tires would calculate to about a 16 percent increase in tire diameter. Increasing the 4.10 axle ratio by 16 percent would dictate the need of a 4.75 axle ratio to match the 37-inch tires.
Do you need to Regear for 35 inch tires?
No, you don’t need to re-gear with 35s. However, definitely plan on a re-gear in the future and fall in love with your Jeep all over again. She loses pep with bigger meats without the regear – especially with the heavier 35″ tires.
How much does a gear ratio change cost?
How much does it usually cost to change your gear ratio, and how easy or difficult is the process? Thanks! $1200-$1500, and 99% of us have a specialty shop do it.
Do bigger tires reduce gas mileage?
For example, larger tires decrease your fuel economy because they are heavier, while smaller tires increase fuel efficiency. Bigger tires also have a higher rolling resistance than smaller tires which means they require more resistance and effort to get them rolling.
